While taking photographs, we often face the problem that unwanted foreground objects (e.g., vehicles, signs, and pedestrians) occlude the main subject(s). We propose to apply image interpolation (also known ) techniques to remove unwanted objects in the photographs and as inpainting to automatically patch the vacancy after the unwanted objects are removed. When given only a single image, if the information loss after the unwanted objects in images being removed is too great, the patching results are usually unsatisfactory. The proposed inpainting techniques employ the homographic constraints in geometry to incorporate multiple images taken from different viewpoints. Our experiment results showed that the proposed techniques could effectively reduce process in searching for potential patches from multiple input images and decide the best patches for the missing regions.
1. Introduction Historical sites represent the culture of a country. As a result, preserving historical sites becomes a more and more important trend in recent years. Today, the technological advancement of digital techniques can help building 3D models of the historical sites under preservation and presenting them by virtual reality. It can keep the original features of the historic sites for a long period of time. Figure 1 shows the computerized models of
the Beipu Township, a national historical site in the Hsinchu County, Taiwan, with 3D models overlaid on satellite images. With the computerized models, visitors can walk
